openingtree VS chess.js

If you know his account on any chess sites you can take a look at it on https://www.openingtree.com/ and find a line he plays that is bad for him, intentionally go for it and have some prep once you there.

I would recommend https://www.openingtree.com/ to start.

Might it be openingtree?

openingtree(https://www.openingtree.com/) will analyze hundreds of your games and let you see, move by move, where you tend to go wrong.

The 3rd thing is that the account is 9 days old. There is some really suspicious behavior here, including his best win being against a 2178 and his worst loss being against a 1214! (according to https://www.openingtree.com/).

Maybe use this website: https://www.openingtree.com/ and filter the games from a certain time frame, like you played that opening exclusively for a week, and then see what happened there, what were the most common positions, and that's the direction I'd take to learn from. Worrying too much about main lines doesn't have much practical value

https://www.openingtree.com/ contains both lichess and chesscom games. Here's Eric Rosen explaining how this works https://www.youtube.com/watch?v=AJ66-HqdpXE

I'm looking at chess.js here : https://github.com/jhlywa/chess.js and it says the latest version is v0.13.4 and it says that laod_pgn is now named loadPgn (I know about load_pgn because I found an interesting example using it on stackoverflow, but that example is ~7 years old).

Thanks! I'm using react-chessboard for the board and chess.js for parsing the PGN and making the moves :)

Just in case anybody is interested I found this on github at this URL: https://github.com/jhlywa/chess.js/blob/master/chess.js

Trying to improve my understanding of javascript and I'm reading through the chess.js code that is on github here (link)[https://github.com/jhlywa/chess.js/blob/master/chess.js] as this code seems to be a standard implementation of chess rules, which interests me.

We'll use a package called chessboardjsx, which will give us an easy way to display the chess game. On top of that we will use the chess.js library to implement moves and how the game should be played.
